GARE) CA 2' 1 it non vrsinnn oann IND-'51? Application filed November26, 1927, Serialltg. 235,959, and. in Italy may 28, 1927.

-My invention relates to visible card indexes, of the kind described inmy co-pending application Serial No. 178,359 of March 25, 1927,comprising supporting elements each provided with a guide, or guides,unsupported along its length for engagin and guiding the card carriers,and has or its 'objectto provide a card carrier of a genersaid uide, andwhich will be simple in manu acture, and comparatively more comact andeasy in operation than card carriers eretoiore in use. V In the annexeddrawings, forming a par of this s ecification, Fig. 1 shows the back ofan em odiment of card carrier according to my invention, Fi 2 shows agroup of Y card carrierslike t at shown in Fig- 1,

viewed from the rear, in engagement with a central guide, Fig. 3beingthe front view corresponding to Fig. 2. Fig. 4 is a perspectiveView showing the manipulation of a group of card carriers within a file.Fig. '5 shows a modified form of card-carrier in front view, Fi '6 beingthe rear view thereof, while Flg. 7 is the front view of the cardcarrier of Figs. 5 and 6, developed in a lane.

.L eferring first to Figs. 1 to 4, 1 is the body.of the card carrier,provided with a heel 2 attached at the-back thereof by means of three ormore wire stitches 3, 4, orthe equivalent, placed on differenttransverse'or The. heel 2 has exactly. the same contour at its upperedge as the body 1, and is provided w1th a central perforation or slot 5whose width D (Fig. 1) substantially corresponds to the width of theguide M (Figs. 2 and 3) preferably consistof a band, tape or the like.

' .Asshown, the upper contour of the slot- 5 in the form of a c1rculararc is connected,

through straight portions 6 and arcs 7, to the lower edge of the heel 2at both sides of the slot. While I have shown straight por-. tions 6intermediate the upper or inner portion of the slot 5 and arcs I mayprovide a direct connection between said portion and arcs withoutdeparting from the scope of my invention. Owing to the symmetry of theslot, the card carrier is adapted to be inserted on aguide M, by merelyturning same in its own plane in either direction card carriers tw beinserted simultaneously on the guide.

I effect this manipulation by interengag- V I ing a group consistin ofthe desired number ally improved character adapted for use with of cardcarriers, as S10WI1 in Figs. 2 and 3, so that they will have the bodies1*, b",- 1,

and heels 2, 2", 2, in an overlapped relation i as shown, andl partiallyturn the group in the planeof the card carriers through the angle placedsidewise with respect to each other that the straight portions 6 on oneside of the slots 5 in the heels thereof will come into alignment witheach other and register with one side of the guide M. In the exampleshown, it will be seen that the ri hthand straight portions 6 are setinto all ment and-register with the right-hand 'e ge of the guide. Byoperating the card carriers with the bodies thereof tilted up out oftheir normal plane, as shown in Fig. 4, the oposite or left-hand flapsof the mterengaged leels will then be engaged with the guide,

upon whichby turning the heels in their own plane in an inversedirection, the card.

tating manipulation and operation ofthe file generally.

On the other hand, a card carrier or a group thereof-may be very easilyremoved from theguide, by merely pulling away the desiredbodies fromtheir support, similarly as'in generally known types of files-of thischaracter.

A- further feature of the described embodiment of card carriersaccording tomy The card carriers shall be so discarriers will be broughtto their normal paratively very small distance-thus facilisituating thewire stitches 3, 4, above referred to, on two parallel lines as stated.Between the side stitches 3, 3 in each carrier,

a comparatively extended abutment or rest line is provided for the upperedge 8' of the next card carrier, to be inserted between the bod andheel ofthe preceding carrier, while in t 1e central portion the stitch 4displaced toward the upper edge thereof determines a sort-of pocket toreceive the central projecting flap 8 of the next card carrier. A morepositive and effective interlocking between the adjacent card carriersis thus provided, than if the wire stitches were on a single line. Ofcourse, a greater number of jstitches 3, l may be provided on twoparallel mes.

The alternative embodiment shown in Figs. 5, 6 and 7, more particularlyrelates to that class of files in which each of the card carriers isoverlapped bythe nextcard carrier and projects a short distance beyondthe overlapping member so as to disclose to the eye of the operator acomparatively considerable part of each card carrier, on which areexposed the necessary memoranda for cursory enquiries, controls and thelike, while a comparatively small covered portion of each card carrieris adapted to receive additional items which are not essential for thecursory enquiries through the file, the files of this class generallycomprisin a very large number ,of card carriers 0' comparatively limitedsizes.

In vertical files of the class just referred to, and more particularlyin files provided with guides unsupported along their length, accordingto my co-pending patent application No. 178,359 above referred to, andhaving card carriers of small sizes, it is I comparatively lessdifficult to provide forthe mutual interlocking of the card carriers,masmuch. as these shde down by the1r own weight along the common gui eand tend to keep themselves automatically in an overlapped andinterengaged relation.

One feature of my invention is thereby to considerably simplify themanufacture of the card carriers, which may each consist as shown inFigs. 5 to 7 of a body and a heel made in'one piece, the heel being cutas an extension of the body, and then folded and suitably fixed theretoat the back thereof.

As shown, 11 is the body of the card carrier, made in one piece with theflaps 12 plicity. 14 and 14 are the front and rear folds respectively ofthe transparent pocket,

mo er? 15, 15 are wire stitches connecting the side collars 13 to thecard carrier. The heel is folded along the'line 18 (Fig. 7) onto-theback of body 11, and 16,16 are wire stitches fixing the heel to thelatter. I prefer to provide a further or central wire stitch 17 to keepthe rear fold 14 of the pocket adherent to the body 11, and to preventsaid pocket against endwise displacements while a card is insertedtherein.

While l[ have referred in the foregoing description to card carriers ofcomparatively small sizes, the feature of a card carrier of the classreferred to, comprising a body in one piece with the heel, may of coursebeembodied by elements of any desired sizes.

ll make no claim herein broadl to the provision of the side collars, wich are claimed in my co-pendin U. S. patent application SerialNo.,235,95 of even date herewith, l desire, however,,.to point out thatthe main feature of the last-described embodiment, namely the eneralshape of the card carrier with a guide of the kind referred to, is anessential of my present invention, as particularly described in theforegoing specification.

What I claim is: ,1

1. lln visible card indexes, of the kind comprising a supporting elementprovided with a guide unsupported along its length, a card carriercomprising a body and a heel member adapted to engage the guide,saidheel member being provided with a central perforation comprising asubstantia'll circular inner portion, symmetrical o lique straight edgesadjoining said circular portion and curved connections between saidoblique straight edges and the free edge of said heel.

2. In card carriers for visible card indexes of the kind referred to, aheel pro- 'vided with a'central slot, said slot comprising asubstantially circular symmetrically disposed inner portion and curvededges between said inner portion and the free edge of the heel.

3. ln visible card indexes of the kind referred to, a card carriercomprising a body and a heel member, the latter being connected to thebody of the card carrier by at least three wire stitches, placed on twoparallel lines.

4. In visible card indexes comprising elements each provided with a ide,a card carrier comprising a body an a heel member made in one piece,said heel member comprising symmetrically arranged flaps, said flapsdefining a central slot formed with a substantially circular straightedges and adjoining said circular inner ortion and curved edges betweensaid straig t edges and "the free edge of said heel member. 1 v

moment 5. In, card carriers for visible eerd indexes of the kindreferredto; in combination, a carrier body, a heel member 'made in onepiece therewlth, a central slot defined symmetrical flaps in seid'heel.v member, wire stitches fixing the said heel in a folded relation ontothe said body, end-open side collars at both ends of the card carriertor the endwise insertion of e transparent pocket and a cardtherethrough.

In testlmony whereof I have hereunto set my hand.
